6.5 inches YES. What t-case do you have. If you have the 242 you might could get away with a 4.5 but you will really have to get your pinion angle right on it.
I think Bouncy had a good write up about Pinion angles on here at one time. May search a lil or PM him for it.
If you have the 231 t-case i would go ahead and pick up a SYE and Driveshaft. HTH

You can get away with up to 7" of lift without an SYE on the older 231 and 242 t-cases which have a short slip. The long slip which has a rubber boot on it would need the SYE.
I can try to find my write up. In the end though, its all about pinion angle and setting it up properly. You need to run the rear axle about 1 degree below what the driveshaft calls for.
On a slip yoke, you need the pinion angle to match the angle of the t-case. If you have an SYE, then the pinion should point AT the rear of the t-case...so the pinion is rotated UP and the t-case would be pointing near level (slightly downward).
Tom Woods site 4x4shaft.com has the tech info I reference about how pinion angles should look. An angle gauge is about 15 bucks at sears with a magnetic base. Very small price to pay to eliminate death wobble and vibes.
Options for pinion angle...Lift via block with angle correction. Shimms. Or cut off the spring pad and get new ones from tractor supply for $10 and reweld them on in the angle you want.
